The Molex 1054111106 is a 6-circuit plug housing from the Mega-Fit 105411 series, designed as a high-current wire-to-wire or wire-to-board interconnect. It uses a 5.70 mm pitch and dual-row layout to carry substantial power in a compact package — the wide pitch gives the contact beams room for the current draw without overheating the insulator. Typical applications include power distribution in white goods, server PSUs, HVAC, and industrial equipment where glow wire compliance (IEC 60335-1) is required for safety approval.
Does this housing include the terminals?
No — the 1054111106 is a connector housing only. The entry for Contacts Not Included is explicit: the male pin crimp terminals must be sourced separately to populate the 6 positions. This is standard for Mega-Fit housings; the buyer orders the terminals to match the wire gauge and current requirement of the application.
Mating connector and polarity
This is a plug housing (male pin side). It mates with the corresponding Mega-Fit receptacle housing that accepts female crimp terminals. The connector is keyed with a locking ramp, so the plug and receptacle only mate in one orientation — there is no polarity reversal risk at the harness assembly stage. The mating half is a 6-circuit, 5.70 mm pitch Mega-Fit receptacle housing (such as the 105411 series receptacle).
What the 5.70 mm pitch means for the build
For a wire-to-wire application, the pitch gives the crimp terminals enough spacing to avoid thermal crowding when the circuit is loaded near its rated current. The dual-row arrangement with the same 5.70 mm row spacing keeps the connector footprint square and efficient for panel cutouts.
